施用麦秸秆对烤烟产质量的影响

在高肥力的土壤上,研究了小麦秸秆还田对烤烟主要农艺性状及产量、品质和病害发生率的影响。结果表明,施N量2kg/667m2和4kg/667m2时,施秸秆的比不施秸秆的烟叶产量分别增加12 2%和13 9%,差异达显著水平;产值分别增加47 65%和39 25%,差异达极显著水平。在不同施N水平下,施秸秆的比不施秸秆的烟株茎围增加,炭疽病和赤星病发生率降低,烟叶中总糖含量提高,烟碱、总氮及蛋白质含量降低。烟叶的香气质、香气量、杂气、劲头和刺激性等有一定程度改善。

Effects of Applying Wheat Straw on Yield and Quality of Flue - cured Tobacco

Effects of applying wheat straw on main agronomic characteristics, yield, quality, and disease occurrence of flue-cured tobacco in fertile soil were studied. The results showed that when 30 kg N/ha or 60 kg N/ha was applied, the yield of flue-cured tobacco in the treatment applied with wheat straw was 12.2% or 13.9 % higher, the output value was 47.65% or 39.25% higher than the control, respectively. At different levels of nitrogen fertilizer application, the stalk circumference, the number of harvested tobacco leaves and the content of total sugar in leaves were increased, the occurrence rates of anthracnose and brown spot were reduced, and the contents of nicotine, total nitrogen and protein in leaves were decreased in the wheat straw treatment. The quality and aroma of tobacco leaves for the wheat straw treatment were also improved, and the offensive taste, strength and irritation were reduced.
